The Clearing
This busy scene shows a Dimetrodon, one of the earliest reptiles, protecting her nest from a plodding fur-covered mammal-like reptile, Cynodontia, and two quick bipedal later reptiles, Euparkeria. Another "cycle" of evolution is represented by the early Rhamphorhynchus in the background, the perched and chicken-like Compsognathus, and the startled Archaeopteryx. The younger birdlike dinosaurs threaten the Age of Reptiles (Triassic), a portend of things to come.
